Encode
======

``\Arokettu\Json5\Json5Encoder::encode(mixed $value, Options $options = default)``

The method aims to be compatible with a simple |json_encode|_ dump.
Important shared features:

.. |json_encode| replace:: ``json_encode($value)``
.. _json_encode: https://www.php.net/manual/en/function.json-encode.php

* |JsonSerializable|_ support.
* Float precision depends on |serialize_precision|_ ini config.

.. |JsonSerializable| replace:: ``JsonSerializable``
.. _JsonSerializable: https://www.php.net/manual/en/class.jsonserializable.php

.. |serialize_precision| replace:: ``serialize_precision``
.. _serialize_precision: https://www.php.net/manual/en/ini.core.php#ini.serialize-precision

The main differences:

* ``NAN``, ``INF``, ``-INF`` float values are supported.
* ``\Arokettu\Json5\Values\Json5Serializable`` interface that takes precedence
  in case you need different behavior for JSON and JSON5.
* No generic object serialization is supported.
  An object must be an instance of ``stdClass`` or ``ArrayObject``,
  or implement ``JsonSerializable`` or ``Json5Serializable``.
  You can replicate the ``json_encode()`` behavior by wrapping an object with ``ArrayObject``.
* The document is always pretty-printed.
* Trailing commas are always used.

Use :ref:`json5_options` and :ref:`json5_objects` to customize your output.

How to prettify JSON
====================

You also need a parser, I will use `colinodell/json5 <colinodell_json5_>`_.
Just parse and dump it::

    <?php

    // adjust to your layout
    require __DIR__ . '/vendor/autoload.php';

    echo \Arokettu\Json5\Json5Encoder::encode(
        json5_decode(
            file_get_contents("php://stdin")
        )
    );

.. _colinodell_json5: https://packagist.org/packages/colinodell/json5

Run the script:

.. code-block:: bash

    php prettify.php < composer.json > composer.json5
